Compare any two graphics cards:
Radeon HD 6990 vs Radeon R9 M295X
IntroThe Radeon HD 6990 makes use of a 40 nm design. AMD has clocked the core frequency at 830 MHz. The GDDR5 memory works at a speed of 1250 MHz on this specific card. It features 1536 SPUs along with 96 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon R9 M295X, which features a GPU core clock speed of 750 MHz, and 4096 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6990 should in theory be much faster than the Radeon R9 M295X in general. (explain)
Texel RateThe Radeon HD 6990 is a lot (approximately 66%) better at AF than the Radeon R9 M295X. (explain)
Pixel RateThe Radeon HD 6990 is a lot (about 121%) faster with regards to AA than the Radeon R9 M295X, and also capable of handling higher resolutions better. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
